WILLIAM S. GRANGER, OF DULUTH, MINNESOTA.

GAS-MIXER.

Application filed Ju1y'13,

To all whom it may concern:

Be it known that I, W LLmM a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Gas-Mixers for Engines, of which the following is a specification, reference being had there n to the accompanying drawing. .j This in'yention relates to feed mixing devices for internal combustiolrengines and has special reference to. a combined mixer and anxiliaryair supply for the gas which forms the feed for such engines.

The principal. objects sought are economy of =fuel and improvement, of the efliciency of theengine to which thedevice is applied. I Otherobjects aresiinplicity in construe tion finstallation and operation. v Still;other objects and advantages of the peculiar 1 construction will, appear in the further description of the invention. .In the accompanying.drawings forming part, of this application and in which like reference characters indicate like parts;

.It, IS tobeundcrstood that this mixing device is to be alled within thegas feedsupply conduitor pipe which leads from the carburetor toil) engine; Suclrfced pipe is clearly illustrated inF ig'. 29f the drawings, lb ing thatportion of the pipeleading from ,rburictcr to: the hitter and 2 .th at .pon tion'l cading from the mixer to the engine.

flange having a smooth or ground face designed. to abut each other either with or without a gasket and held tightly together by suitable through bolts in opposed holes 'thiss'ame formand provided with opposed holes 5 5, is positioned intermediate of the ends of the portions 1 and 20f the feed pipe or condult, and thus becomes a cooperative part thereof. The ends of the pipe and the mixer body are held togetherby the through bolts as. above described.

The face of the body portion 3 of the mixer toward the endQof the pipe, is bored out forming a chamber 6 concentric with the bore of the pipe though, slightly smaller in diameter, and between the chamber and opposite outer, face. of the body .3 is left a in which is a series of radially positioned holes 8, preferably six in number.

In. the circumferential Wall of the chamber 6 is screw threaded a cylindrical housing 9 having a thinend wall 10 like the end wall 7, and through which holesll similar to theholes 8.are formed. l When the housing is screw threaded within the body 3 and' in operative position, it is preferred to have the holes 8 and 11 in staggered'relation to each other, that is, not opposite, theobject of which is-to create 2lS t;( 1tllOl1S .2t route as possible for the gas as it passes through the mixer.

Within .thecenter: of thewall 7 is a bearadjustable asdesired, and in the center of the wall-10 is a similar plug 13 preferably made adjustable bynbeing screw threaded M thereon, whereby the any desired adjustment. the concaved ends of the within the wall 10 andfhaving a jam nutplug may be set at Intermediate of bearing plugs 12 'ingp1ug12whieh may'or may. not be made and 13 is rotatably mounted the mixing fan v wheel, 15, the blades of which arelset at an angle, similar tothose of .alboat propeller,

, whereby the passingv of. gas through the air to the gas as it passes through the mixer, and, as it is thoroughly incorporated with the gas by the rotation of the heel in the mixer, the principal objection to thus addw ing air to the gas just before entering the cylinder, is avoided, as it is Well known that the addition of air in the ordinary manner is to a large extent impractical.

-1 have illustrated a common spigot valve at 18 controlled by a suitable 'lever 19 and rod 20 which may lead to any convenient place for manipulation by which the amount of air admitted to the mixer may be conveniently governed.

While I have shown the'air supply as coming from no place in particular, except that it is outside of the conductor pipe or conduit, it is evident that in the event of the mixer being used in connection with a Water cooled engine, the air pipe may lead from the top of the radiator from whence air having more humidity therein than the ordinary atmosphere, may he had, but this I do not claim as new with me and forms no part of the present invention.

From the foregoing it is apparent that I have devised means whereby air may be added to the mixture en route from the carbureter to the engine, and such additional air not only thoroughly incorporated With I the mixture, but the mixture itself considerably improved by the motion of the mix ing Wheel. Y

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is-

A gas mixer for a separable gas conduit for engines comprising a single-piece principaLbody member held intermediate of the separable portions of the conduit and forming a dooperative part thereof and having a tangentially disposed port therein, communicating with the outside atmosphere, a central cylindrical screw-threaded chamber within the principal body portion'communica ing' With the port and having a plurality of holes in one end thereof, and a second cylindrical chamber screw-threaded externally and engageable within the chamber in the principal body portion but not closing the port therein, said second chamber having one head formed integral therewith and having a plurality of holes therein and a mixing wheel supported by and intermediate of the heads,

In. testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
